SIDE FRAM AND BRAKE SUPPOR STRUCTURE Claus J. Werner Clasen, Chicago,Ill., assignor to American Steel Foundries, Chicago, Ill., a corporationoi' New Jersey Application July 17, 1947, Serial No. 761,598 6 claims.(ci. 18s-'205) My invention relates to railway car trucks and hasparticular reference to novel support means for the truck brake rigging.i

The principal 'obj ect of the invention is to provide a bracket which iscast integral with the side frame and which will serve as a support forseveral parts of the brake mechanism of the truck. v

A further object oi the invention is to design a bracket of the typedescribed possessing the characteristics of light weight, necessarystrength and simplicity of design, and economy of manufacture. y

A still further object of the invention is to devise a novel support fora structure carrying a portion of the brake mechanism.

These and other objects of the invention will be apparent from thespecification and drawings, wherein:

Figurel is a fragmentary side elevation of a truck structureincorporating my novel invention;

Figure 2 is a horizontal sectional view taken substantially in the planeindicated by line 2-2 of Figure 1 showing the bolster as associated withthe side frame; and t Figure 3 is a sectional view taken in the planesubstantially as indicated by line 3-3 of Figure 1..

Referring to. the drawings in detail, the inven tion is illustrated inconnection with a railway car truck comprising the side frame 2(Figure 1) havinboard column member wall I8, the web 30 being oiset asat 3i (Figure 2) adjacent the column to afford clearance for theassociated inboard bolster lug I4.

At thevupper corner of the web 30 remote from the frame is formed ajawlike structure, generally designated 32, comprising a pair ofdiagonally aring a compression member 4,`a tension member 5,

and an integral upright column 6 adjacent each end of the frame andmerging with said compression and tension members and defining therewitha bolster opening 8 (Figure 1) centrally of the side frame and a windowopening I0 adjacent each end of the frame.

A bolster I2 (Figure 2) may have an end disposed in the bolster opening8, the bolster being spring-supported from the side frame in the usualmanner, as will be readily understood by those skilled in the art. Thebolster may be provided at each side thereof with inboard and outboardinterlocking gibs or lugs I4 and i6 embracing the v adjacent columntherebetween.

Each column 6 may be of U section comprising inboard and outboard websor walls I8 and 20 joined byv an intermediate wall or web 22.

On the inboard side of the frame at the juncture between each column andthe compression member is formed an integral bracket 28, (Figures 1 and3) the bracket comprising a vertically disposed laterally extendingsubstantially rectangular web 30 integrally formed with the inboard sideof the compression member and the adjacent ranged vertically spacedsubstantially parallel webs or flanges 34, 34 extending from one side ofsaid web 30 in a direction toward the adjacent end of the frame andforming a throat 36 adapted to seat the top chord of a loop hanger (notshown) in the usual manner.

The flanges 34, 34 are provided with vertical openings 38, 38 forreception of a pin (not shown) for securing the associated loop hanger,as will be readily understood by those skilled in the art.

The upper flange 34 is connected to the compression member of the sideframe by a laterally extending arcuate web 40 merging at opposite endswith the inboard side of the compression member and said upper flange34. A vertical rib 4i joins the top surface of the upper iiange 34 andthe top surface of the web 40. The web 40 also merges at the edgeadjacent the bolster opening, with the top edge cf the web 30, thusstrengthening the connection between the web 30 and the side frame. Tolighten the structure the web 30 may be cored away as at 42 (Figure 3).

On the web 30 beneath said bolster structure 32 is mounted a bracket 44ailording support for a tubular member, support or crosspiece 46extending between the side frames of the truck and constituting a basalcontact member for engagement with and actuation of a load compensatingdevice forming part of the brake mechanism. The load compensating deviceis not shown inasmuch as vit forms no rpart of the present invention.Suiiice it to say that the crosspiece 46 serves as an actuating part forsaid load compensating device.

The bracket 44 comprises a vertical web or mounting plate 48 seatedagainst the web 30 of the bracket 28 beneath said structure 32. At oneend of the web 48`is formed a cylindrical housing 50 closed atth'efendadjacent the web 48 by a wall 52, therwall '52 merging with said web 48. Within the lhc'iusing are disposed a pair of axially y spacedcylindric'a-lv resilient bushings 54, 54 such as rubber, said v'bushingsbeing sleeved over the adjacent-fend of the crosspiece 46 and affordinga resilient support therefor. It will be noted that the cylindricalhousing is formed at its open end with a pair of axially spaced inturnedannular flanges 55, 55, the flanges being spaced from the end of thetubular member 46 whereby said tubular member is afforded universalangling with respect to` the bracket 44 against the compression of theresilient bushings 54.

Horizontally disposed reinforcing gussets 58, 56 connect the wall 52 ofthe cylindrical housing 50 with the opposite sides of thev web 48 of thebracket M.l

structure connected to the inboard side of said column and member, asubstantially vertical wall beneath said structure connected theretoI'he brackets 28 and 44 are connected to each A other by a plurality ofbolts 58. 58 extending through aligned openings in the webs 30 and 48 ofthe respective bracket.

To reduce the stresses on the bolts, the web 30 ofthe bracket 28 isprovided with a horizontal ledge or flange 60 at the bottom edgethereof, said ledge extending laterally from one side of the web 30beneath the structure 32 and affording a seat as at 62 for the lower,`edge of the web 48 of the bracket 44. At the juncture between the web 30and the ledge 60, the web 30 may be cored away as at 64 (Figures 2 and3) to insure a close iit for the web 48 of the bracket 44. For the samepurpose the web 48 of the bracket 44 is provided on the surface facingthe web 30 with a vertical flange 66 which seats against the verticaledge of the web 30 as at 68. 'I'he ilange 66 on the side opposite thatwhich seats against the web 3D is connected to the adjacent gusset 56.

It is to be understood that I do not Wish to be limited by the exactembodiment of the device shown which is merely by way of illustrationand not limitation as various and other forms of the device will, ofcourse, be apparent to those skilled in the art without departing fromthe spirit of the invention or the scope of the claims.
